Patented May 7,1912.

To all 'whom it may concern.:

Be it known that I, THUR PRIDDLE, citizen of the Unitedy States, residing at San Francisco, in the connty of San Francisco and State of` lCalifornia, have invented certain new and useful- Improvements in Corner-Protectors; and I do declare the following to be a full, clear, andv exact description of the invention, such as willenable others skilled inthe art to which it appertains to inakcand use the same. t

This invention relates t improvements in protectors for plaster or concrete corners.

One object ofthe invention is to provide a corner protector adapted for use in con nection with wooden 'fra-me work comprising a sheet 'metal plate having'an integral means whereby the saine may be firmly secured to the frame work and braced without the use of separate Afastening dev-ices.,

Another object is to provide a protector of this character having formed therein near its outer edge, a series of anchoring devices so arranged that the plaster or concrete at the extreme outer portion of the corner will be fully protected.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims. l

In the accompanying drawings: Figure 1 is a side view of a' section or portion of the protector; Fig. 2 is a horizontal sectional- `view thereofshowing the same applied to the y corner of a frame structure for protectingV the plaster thereon; Fi 3 is asimilar view showing a slightly di erent application of the protector and -a modified "form of the outer edgeior bead of the same; F ig. .4 is a horizontal sectional view of, the protectorshowing stillfanother form f `beadgvFig.J 5

' is a plan view'of a blank showing the Inanner in which two protectors are cnt r staiinced4 therefrom; Figs. 6, 7, 8 and 9 are similar views showing dierent 'forms' of fastening and bracing teeth or lugs.

In the embodiment ofthe invention as shown in Fig. l ofthe drawing, l denotes a plate or strip of heavy sheet metal which may be of'any desired-width and fornied'in any suitable length.

- On one edge of the strip lisformed a tion of the protector each alternate tooth 2.

I forms a fastening tooth and is adapted'to be driven into the frame work of the structure. The teeth 3 and 4 between the fastening and for'this purpose are bent laterally 1n opposite directions and at a suitable angle for closely engaging the material at the cor ner of the frame work. 1

In arranging the protector for use the bracing'teeth or lugs 3 are all bent in one direction, while the alternate bracing teeth or lngs'4 are bent in the opposite direction as clearly shown in Fig. 2 of thendrawing. When the teethhave thus been arranged the protector is applied to the corner of the frame work and the fastening teeth 2 driven yor forced into said corner until the laterally bent bracing teeth or lugs 3 and 4 vcome into engagement with the opposite outer surfaces of the fraine Work thereby securely fastening may be left. plain7 but is preferably pro- `-vided with a finishing bead as shown.

' In Fig. 2 of the drawing ist shown a bead 5 which is formed by bending or upsetting 4the outer edge of the inetal in the form of 'a flattened roll, while in Fig. 3 of the drawar manner as the bead 5 but having an elongated shape er form.k

4teeth 2' are intended toserve as bracing lugsv ing is shown a bead 6 constructed in a simi- Inl 4 of the drawing is shown a bead i '7 which is constructed from a separate-strip of metal bent or folded upon itself and clenched to the straight outer edge of the protector. The separately constructed bead 7 is preferably formed of non-corrosive rrietal.

In the body portion of the protector near the outer edge of the same is formed a series ofA anchoring lugs 8 which are preferably provided with curved outer edges and are formed by cutting curved slits in the body of the protector-and bending the cut metal laterally in 4opposite directions. In thus forming the anchoring lugs 8, apertures. are provided in the body portion of the protector through which the plastic material passes, thus serving as additional means for anchoring the material.

In Figs. 5 to 9 of the drawings is shown `the manner in which two protectors may be cut or stamped from a single strip of material at one operation, thus expediting the construction of the protectors. 6 and 7 the fastening and bracing teeth have the same general construction but are of slightly different shape. In Figs. 8 and 9 the metal is cut to form bracing lugs 9 between each of which is formed two fastening teeth l0. The lugs 9 when' thus formed may be of greaterv or less length or width as shown in the two gures referred to thereby spacing the teeth 10, a greater orlless distance apart. When the lugs and teeth 9 and 10 are thus formed and the two sections of the metal separated, each of said sections i will be provided with a series of lugs 9 adjacent to each opposite side or end of which is arranged a tooth 10. Between the teeth y, in Figs. 8 and 9 the successive lugs 9 will'be.

10 will be formed espace of greater or less width according to the width or length of the lugs 9 of the opposite protector sections which were cut from and formed said spaces.

In the construction of the protector shown bent in opposite directions at the desired bangle while the fasteningteeth l0 between the lugs will be forcednto the frame work of the structure tlf/e/nanner described.

,From the foregoing-description taken in connection with the accompanying drawings, the cohstruction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion 'and VJthe minor'- details .of construction may be resorted t-o without departing from the principle orA sacrificing lany of the ativantages of the invention as defined in the ap,

pen ded claims.

In Figs. 5,

- Having thus described my invention, what tween said fastening teeth and adapted to' be bent laterally in opposite directlons to the desired angle, a finishing bead arranged on the outer edge of said protector, a series of anchoring lugs formed in the body of the protector and also bent laterally in opposite directions therefrom.

3. A corner protector comprising a strip or sheet of' metal, a series of pointed fastening teeth formed on the inner edge thereof, a series of bracing lugs formed on said edge between said fastening teeth and adapt". ed to be bent laterally in opposite directions to any desired angle, a series of anchoring lugs struck from the body portion of the protector near its outer edge and bent lat. erally in opposite directions, thus forming apertures in the protector said lugs having curved outer edges, and a finishing bead formed on the outer edge of the protector inA the form of a roll.

4. A corner protector comprising a strip of metal, three series of projectionsextending from the inner edge of said strip,'the intermediate series being disposed in the planeof the body. of the strip and forming fastening spurs to be driven into a support and. the two side series forming braces to engage the support, whereby the protector will be supported and braced in operative position. y

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
